Eliminates the need for a tantalum cap on the input to the CCR. That in turn eliminates the need for a diode.
Same with the output of the CCR.
You do not need a capacitor because of the nature of the load.
With no output cap to reverse bias the regulator, no "protection diode" is needed. Keep it simple.
16 ga. wire would suffice, but I'd use 14 ga. stranded and a plug/socket right at the lamp.
Okay, now I'm excited because I actually understand all that.

What I'm not sure about (among many other things) is what the 15w. 660's are actually going to be pulling current-wise. They're rated at 1500mA, so if I'm running them conservatively are they pulling a bit over an amp or so each, or are these things actually meant to be run at 750mA? (I'm cautious of power ratings, I remember audio amps that were in reality about 30 watts RMS being rated at 600 watts "intermitent peak-to-peak" or some other hogwash.):wtf:

If the reds are indeed capable of pulling an amp and a half each, my 5.5 amp power supply isn't as overkill as I'd thought.
